Filed: 1928-03-28
Abstract: 306,308. Sykes, Ltd., W., and Wycherley, W. J. March 28, 1928. Balls.-A casing for a football, basket ball, volley ball or other inflated ball is formed of a number of panels or sections sewn together by their edges and having a vent formed in one of the panels, and the edges of the vent are brought tightly together by the inflation of the ball and are retained by a series of hooks and eyes secured to the inside of the casing. The casing shown in Fig. 1 is formed of two panels A, B, each panel being made by sewing together two sections. An opening slit 11 terminating in small holes 14 is provided for the insertion of the usual deflated bladder. Hooks and eyes 15, 16, Fig. 8, are secured by means of fabric strips 19, 20, to the inside of the casing and when hooked together maintain the opening slit 11 in the closed position. The edges of the vent 11 are brought tightly together by the internal pressure. A flap 28 protects the bladder from injury by the hooks and eyes. The bladder is provided with a non-return valve of usual form screwing into a washer 13 secured to the interior of the casing. An orifice 12 in the casing permits access to the valve for inflation purposes.

Abstract: 177,803. Poebing, O., (Assignee of Wielich, R.). April 1, 1921, [Convention date]. Drawings to Specification. Motor power plant.-In a hydro-electric plant the load is taken by a number of turbines of one group, each working under full load constant conditions and one or more regulated turbines of a second group which supply the peak variations. On an increase or decrease of the load equal to one turbine unit, a turbine of the first group is fully cut in or out, as by means of a device connected with the masking blades of the regulated turbine. The regulated turbine may have 1.2 times the output of the constant turbine. On large variations of load the supply to all the turbines is regulated as in the manner described in Specification 174,950, the regulated turbine however continues to take up small variations.

Abstract: Monoazo dyes and soluble metal compounds thereof; acid wool dyes, dyeing with.-Monoazo dyes are obtained by coupling diazo compounds with amides of 5-pyrazolone-3-carboxylic acids; the latter may be substituted in the 1-position of the pyrazolone ring and in the amide NH2 group.  Certain of the products, e.g. those obtained from o-oxydiazo compounds may be converted in substance or on the fibre into complex metal compounds by treatment with agents yielding metals.  The following examples are specified.  (1) The dyestuff aniline --> 1 - (41-sulpho) phenyl-5-pyrazolone-3-carboxylic acid amide dyes wool and silk level powerful golden yellow shades of good fastness.  (2) The dyestuff 4-nitro-2-aminophenol-6-sulphonic acid --> 1 - (41-sulpho) phenyl-5-pyrazolone-3-carboxylic acid amide dyes wool red-brown shades which on after-chroming become very fast red-orange; the chromium compound prepared in substance gives very uniform orange-brown dyeings on wool.  (3) The dyestuff 1 : 2 aminonaphthol-4-sulphonic acid --> 1-phenyl-5-pyrazolone-3-carboxylic acid anilide dyes wool brown-red shades which on after-chroming become very fast violet.

Abstract: 1352351 Machine tool control SIEMENS AG 19 April 1971 [26 March 1970] 9981/71 Heading B3B [Also in Division G3] A contour 3 is produced from a blank 4 on a lathe 1 by a programmed numerical control system employing a DDA-interpolator 9 energizing stepping motors 7, 8 positioning a carriage 6 for a cutting-tool 5. An adaptive logic unit 10, in the line to motor 8, controls the depth of cut in dependence on the torque on the spindle of the lathe. The motor pulses are blocked with an increase in torque above a preset value and fed to an overrun counter 11; for a further increase of torque, pulses are fed to the motor 8 to reduce the depth of cut. When the preset torque value is not attained, the depth of cut is increased until the preset torque is attained, or the contour reached. The DDA interpolator comprises integrators 92-94 and a pulse generator 91 connected to a logic unit 95 providing pulse trains #X and #Z to the motors whereby a circularly or linearly interpolated path element is traversed in time #t. The end of the interpolation is established when the set values are attained in stores 13, 14. When the path deviates from the programmed contour, the tool path velocity is kept constant by modifying the effective path length, stored in the integrator 93, in dependence on a comparison, by a device 12, of the deviation held in the overrun counter 11 and the final path value held in the store 13.
